摘要

This is designed to protect groundwater wells installed above Sealed inside the digital marker for water meter with a moisture-proof function Conventional Sealed ball being placed outside the upper protection installed or connected to a separate signal embedded in the hermetically sealed so as to protect the upper ball device itself, eliminating the inconvenience of securing a place to install a digital marker device relates to a ball device Sikkim was the purpose of simplifying the configuration of the course should be easy to check the instructions for the water meter is easy to maintain. ; A digital marker for water meter installation according to the intended groundwater wells described above hermetic protection ball perforated opening device that allows you to configure the meter window, you can see the character of a meter digital marker and the opening has to be fixed into the den was processed tempered glass. Opening and the combination of the digital marker dew on a separate closed space formed by the reinforcement that is in a closed upper protective ball installed in an opening in a humid space inside the inner surface of a glass viewing window to be screwed by inserting a rubber packing between the Frost or join meter was impossible to avoid. If a particular Despite this configuration signed dew or frost on the windows inside space was set to the injection port for injecting fluid for removing the high temperature dry air or remove them separately.
